Abstract

This study aims to develop a science e-module through the Problem Based Learning (PBL) model on Static Electricity material and test its effectiveness on the problem-solving skills (KPM) of grade IX students. The method used is Research and Development (R&D) with the ADDIE model (Branch, 2009). The research subjects were 30 students of class IX A SMP Negeri 11 Mimika. The instrument is in the form of a 11-item KPM test (Arikunto, 2010). The analysis technique used n-Gain descriptive analysis of percentages and categories on the Likert scale (Hake, 1999). The results of the study showed: (1) E-modules were declared very feasible to use with an average material feasibility of 97.68%, media feasibility of 96.72%, teacher response of 98.33%, student response of 96.39%, and the average overall feasibility of e-modules based on validator assessments of 96.80% (Ministry of National Education, 2008). (2) The e-module effectively increased KPM with an average pre-test of 38.98 to 71.98 in the post-test and n-Gain of 0.54 in the medium category. Conclusion: the PBL model science e-module is feasible and effective in improving students' problem-solving skills in Static Electricitymaterial.

Abstract

This study aims to design and develop Student Worksheets based on a discovery learning approach, supported by PhET Interactive Simulations  media, and to examine their design, feasibility, and practicality in the context of electricity at the high school level. The LKPD development process follows the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, which encompasses the stages of analysis, design, development, implementation, and evaluation. The average obtained from the expert validation results is 87.50%, based on three assessment aspects, and is declared to be suiTabel for use. Meanwhile, the feasibility validation by media experts yields an average value of 79.68% across four indikators, indicating that the LKPD is ideal for use. Furthermore, the results of the field trial conducted by students are 82.84%, which is also classified as very appropriate. Based on the average value, it can be said that the physics LKPD based on discovery learning, supported by PhET.
